If we don't keep the current behaviour of "Set Range" as an
option (i.e changing the range doesn't scale) then I can't see
much need to keep "Set Range" either.  

Perhaps a better way to allow for current Time Track usage 
would be a method to move all envelope points at the same time, 
like a horizontal bar or similar. That's been requested for Envelope 
Tool.
